Preparation of equipment and compatibility check

Before you start actively connecting devices, you need to make a preliminary diagnosis of existing equipment. Make sure your laptop has the appropriate ports for video output, and Xiaomi TV has free inputs. Most modern models have HDMI connectors, which are the de facto standard for transmitting digital video and audio in high quality.

If you plan to use a wireless connection, it is critical that both devices are on the same LAN. IP-Addresses to both devices, and there should be no isolation of customers between them (AP Isolation, which is common on guest networks.Check out the operating system version on your laptop, as in Windows 10 and Windows 11, the broadcast tools are built in by default, whereas on older versions additional drivers may be required.

Not all HDMI cables are the same: 60Hz 4K image transmission requires a High Speed or Premium High Speed certified cable. Using old or damaged cables can cause the picture to flash, lose sound or automatically drop to 720p.

Wireless connection via HDMI cable

The most reliable and easy way to display an image from a laptop to a Xiaomi TV is to use a cable. HDMI. This method provides uncompressed video and sound transmission at the same time, making it ideal for watching movies in high bitrate or games where minimal input lag is important. To start, connect one end of the cable to the laptop’s video output and the other to any free port. HDMI on the back or side panel of the TV.

After the physical connection, you need to switch the signal source on the TV. Take the Xiaomi remote control and find the login select button, often marked with an arrow square icon or Input signature. In the menu that opens, select the port number you plugged the cable into, such as HDMI 1 or HDMI 2. If done correctly, your computer's desktop will appear on the screen.

It is important to note that modern laptops often come with Mini HDMI or USB Type-C video-enabled ports. In such cases, you will need an appropriate adapter or adapter. Make sure the adapter supports video transmission, as some cheap USB-C cables are only for charging and data transfer, but not video.

Setting up the screen mode in Windows

Once the TV detects the signal, Windows will offer several options for using the second display. To quickly access these settings, press the Win + P keyboard key combination. You will see a project menu where you can choose how the image will work: duplicate, expand or use only one screen.

• 🖥️ Computer screen only: the image is displayed only on the laptop, the TV screen goes out or shows a message about the absence of a signal.
• 🔄 Repeated: the picture on the TV completely copies the contents of the laptop screen, which is convenient for presentations.
• 📐 Expand: The TV becomes an extension of your desktop, allowing you to drag and drop windows between screens, which is ideal for watching videos while you’re working.
• 📺 Only the second screen: the laptop screen goes out, and the image is displayed only on the TV, which saves system resources.

To adjust the image quality, go to the Settings → System → Display menu. Here you can change the screen resolution to match the native resolution of your Xiaomi TV matrix. If the text on the TV looks too small or, conversely, huge, use the Scale slider and markup, setting a value of 150% or 200% for comfortable reading from the sofa.

💡

Expand mode allows you to use the TV as a second monitor, leaving the laptop free for other tasks, which greatly increases multitasking.

Wireless streaming via Miracast and Wi-Fi Direct

Miracast technology allows you to transmit images wirelessly using a direct Wi-Fi Direct connection between your laptop and your TV. On Windows, this feature is called Connection. Make sure your laptop supports this technology (most Windows 10/11 models support). On a Xiaomi TV, the feature is often built into the system or available through the Wireless Display app.

To start the broadcast, open the notification center in Windows (click Win + A) and select Project or Connect. The system will start searching for available devices. Your Xiaomi TV should appear on the list. Click on it, and in a few seconds the image will appear on the big screen. Note that there is a slight delay when connecting wirelessly, so this method is not suitable for dynamic games.

The quality of wireless transmission is directly dependent on the load of wireless air. If your network is running many devices or neighboring routers cause interference, the picture can slow down. In this case, try to turn off other heavy downloads or reconnect devices to the 5 GHz network if your router and laptop support this frequency range.

Use of built-in Chromecast and Google Home

Because Xiaomi TVs run on Android TV, they have built-in support for Google Cast (Chromecast built-in) technology, which allows you to stream content from Google Chrome or compatible apps directly to your TV, a method that doesn’t require complex network setup and often works more stable than Miracast, especially for streaming video.

To use this method, open the Google Chrome browser on your laptop. Click on the three dots in the top right corner of the menu and select Translate... (Cast.) In the window that appears, you will see a list of available devices. You can choose to stream the entire tab, a specific window, or the entire desktop. Once you select the Xiaomi device, the data will start transferring.

💡

To reduce latency when broadcasting wirelessly, close the unnecessary tabs in the browser and stop downloading files on other devices on the network.

The advantage of using Chromecast is that it can control playback from a laptop while the TV is simply displaying stream, and many streaming services are optimized for this technology, providing better picture quality than simply duplicating the screen.

Third-party broadcasting applications (AirPin, LetsView)

In some cases, standard operating system tools may not work properly or are not supported by older laptop models. Third-party applications come to the rescue. For Xiaomi TVs, the AirPin (PRO) or built-in Cast app is a popular solution. You need to install the client part of the program on your computer, and the server one on your TV from the Google Play store.

Another great option is LetsView, which works on a variety of platforms, including macOS and Windows, which allows you not only to duplicate the screen, but also to control the computer from a phone connected to the same TV, installing such applications takes a couple of minutes, and the interface is usually as simple as possible for a quick start.

Solving Sound and Image Problems

A common problem when connecting a laptop to a Xiaomi TV is the lack of sound or its de-synchronization with video. If the sound is not coming through the TV, check if the default audio output device is selected. In the Windows Sound Control Panel, find your TV, right-click it, and select Use by default.

If the image on the TV screen does not occupy the entire area (the edges are trimmed), you need to change the aspect ratio settings. On the Xiaomi remote, click the menu button (three dots or gear), go to Settings → Image → Image size and select Just Scan mode, Screen size or 16:9. This will remove the black bars and stretch the picture over the entire matrix.

⚠️ Note: If you are connected through HDMI screen goes out and lights up again, maybe the cable doesn't support the required bandwidth for the selected resolution. Try to reduce the screen refresh rate in the Windows display settings from 60 Hz to 30 Hz or replace the cable with a better quality.

In situations where your laptop can't see the TV on the network, check the firewall settings. Antivirus or built-in Windows protector can block device detection on the public network. Make sure the network type is set as Private, not Public, to allow detection.
